ERFURT, Germany-Interim data from a randomized phase III study show that MCP (mitoxantrone [Novantrone], chlorambucil [Leukeran], prednisolone) with or without rituximab (Rituxan) is active in advanced indolent lymphomas. Michael Herold, MD, reporting for the Ostdeutsche Studiengruppe Haematologie/Oncologie (OSHO), said, "The response rate of 81% is within the range of that seen with standard therapies. The complete response (CR) rate of 40% was highly encouraging, particularly given the multi-institutional setting of this study. To date, no significant change in response has been seen with the addition of rituximab to MCP, but further follow-up is needed to determine if the addition of rituximab will improve the duration of response."
